template< class charT > bool isspace( charT ch, const std::locale& loc ) { return std::use_facet<std::ctype<charT>>(loc).is(std::ctype_base::space, ch); } |
[edit] Example
Demonstrates the use of isspace() with different locales (OS-specific).
#include <iostream> #include <locale> int main() { const wchar_t EM_SPACE = L'\u2003'; std::locale loc1("C"); std::cout << "isspace(EM SPACE, C locale) returned " << std::boolalpha << std::isspace(EM_SPACE, loc1) << '\n'; std::locale loc2("en_US.UTF8"); std::cout << "isspace(EM SPACE, Unicode locale) returned " << std::boolalpha << std::isspace(EM_SPACE, loc2) << '\n'; }
Output:
isspace(EM SPACE, C locale) returned false isspace(EM SPACE, Unicode locale) returned true
